Description
Technical field
The utility model relates to blade processing technical field, is a kind of blade positioning fixture specifically.
Background technology
In aero engine turbine blades manufacture process, because blade profile is complicated, body is less, fixture location clamping difficulty.Conventional processing methods adopts low-melting alloy to pour into a mould an auxiliary process platform at blade, is transformed on process area by machining benchmark, then carries out the processing of all the other machined sequences based on this process area.Need to increase by least 4 road additional process owing to increasing auxiliary process platform, just need accordingly to increase frock quantity and manufacturing cycle and cost, and low-melting alloy cast damages with melting to exist blade, increase pollution etc.
Summary of the invention
For solving the problems of the technologies described above, the purpose of this utility model is to provide a kind of blade fixture, can realize precision positioning and the clamping of blade, replaces the method for traditional low-melting alloy casting auxiliary process platform, special procures the new clamp structure of research and meet field demand.This fixture meets following technical requirement: (1) accurate positioning, rational in infrastructure; (2) clamping is convenient, stable, and operability is high; (3) produce without extra-stress, and can not damaged blade.
The utility model make use of fixture principle of six-point fixing, 2 points bottom blade tenon, 1 point, side 2 point bottom blade, the locate mode that blade afterbody is 1, realizes precision six point location of blade, adopts four sides jaw type clamping mode to tenon listrium simultaneously, increase clamping stability, adopt the mode of synchronous clamping at listrium above-below direction, eliminate the generation of clamping stress, adopt the mode of synchronous clamping to realize the fixing of blade left and right directions equally at afterbody.This jig main body structure is divided into 5 parts: Part I is base, is the basis of whole fixture; Part II is localization part, three parts before, during and after being divided into, and realizes tight six point locations to blade; Part III is clamp system, is divided into the clamping of four sides, front end and afterbody bilateral clamp system, fixed blade position and additionally do not produce clamping stress.This clamp structure is rationally compact, simple and convenient, is connected reliably with machine tool.Concrete technical scheme is:
The accurate six point positioning fixture structures of a kind of blade, comprise base, base are arranged 6 anchor points; Anchor point is arranged on 2 points bottom blade tenon, 1 point, side 2 point bottom blade, blade afterbody 1 point; Also comprise clamp system, described clamp system is divided into the clamping of vane nose four sides and blade afterbody bilateral clamp system; Concrete structure is: afterbody locating centre is fixed on base, and middle clamp plate and lower plate are sleeved on guide pillar, and guide pillar is fixed on base; Lower plate is arranged the top and interfix part of 2 prelocalizations, interfix part is arranged 2 interfix points; Lower plate is also arranged two side keepers and 1 afterbody locating centre; Between train wheel bridge and middle clamp plate, nail pressing is set; Left clamping plate are followed closely with supporting and are abutted, and other one end of supporting nail arranges spring; Right clamping plate are followed closely with supporting and are abutted; Left tail clamping plate and right tail clamping plate arrange screw.
The beneficial effects of the utility model:
The utility model eliminates and carries out to blade blade the mode that alloy casting auxiliary process platform positions clamping, decrease 4 procedures of traditional diamond-making technique, eliminate the expense more than 10 ten thousand yuan of low melting point alloy, to optimized process flow, promote processing and manufacturing technology, to shorten the lead time significant.

Detailed description of the invention
Illustrate the utility model below in conjunction with accompanying drawing, as Figure 1-Figure 5, the utility model comprises base 1, base 1 is arranged 6 anchor points; Anchor point is arranged on 2 points bottom blade tenon, 1 point, side 2 point bottom blade, blade afterbody 1 point; Also comprise clamp system, described clamp system is divided into the clamping of vane nose four sides and blade afterbody bilateral clamp system; Concrete structure is: afterbody locating centre 5 is fixed on lower plate 6, and middle clamp plate 7 and train wheel bridge 8 are sleeved on guide pillar 14, and guide pillar 14 is fixed on base 1; Lower plate 6 is fixed on base 1, lower plate 6 is arranged 2 prelocalizations top 2 and interfix part 4, interfix part is arranged 2 interfix points 41; Lower plate 6 is also arranged two side keepers 3 and 1 afterbody locating centre 5; Nail pressing 15 is set between train wheel bridge 8 and middle clamp plate 7; Left clamping plate 9 abut with supporting nail 16, and other one end of supporting nail 16 arranges spring; Right clamping plate 10 abut with supporting nail 16; Left tail clamping plate 12 arrange screw 17 with right tail clamping plate 13.
Clamping process of the present utility model:
(1) before clamping parts, first to ensure that lower plate 6, middle clamp plate 7, train wheel bridge 8 are in off working state, and ensure that middle clamp plate 7 is free to slide on guide pillar 14; Tail centre 11 is in releasing orientation; Left tail clamping plate 12, right tail folder 13 is in and maximumly opens distance.
(2) blade is placed on fixture relevant position, ensures on blade that each anchor point and prelocalization are top 2, side keeper 3, interfix part 4, afterbody locating centre 5 contact, leaf position is determined, guarantee blade six point location;
(3) then rotate tail centre 11 to be fixed on by blade on afterbody locating centre 5, left clamping plate 9 are close on the left of part under spring force by supporting nail 16, and right clamping plate 10 are by the right side of screw 17 compressing component; Rotate nail pressing 15 and make lower plate 6 and middle clamp plate 7 relative movement, thus the top and bottom of compressing component, because lower plate 6 and middle clamp plate 7 produce relative motion in guiding situation, extra-stress is not produced to parts fixation, by screw, whole clamping plate and pedestal is firmly linked together after clamping; In like manner, at afterbody, tighten screw and left tail clamping plate 12 are produced relative motion with right tail clamping plate 13 on slide rail, two seal faces of Clamp blocks afterbody, this process is also the process of similar pliers clamping, eliminate clamping moment by the slippage of track, finally by screw, left tail clamping plate 12 are fixed on foundation base with right tail clamping plate 13, achieve whole clamping processes of part.
(4) whole fixture achieve part in front end, middle part, afterbody positioning and clamping, accurate positioning, clamping is convenient, safe and reliable, greatly improves the rigidity of part, is designed with important reference function to the fixture scheme of this type of part.
